I think it's a great idea I have two sons and they both have the same middle name. They are FN MN Joseph LN and if we have a girl she will be FN MN Marie LN. It's a family tradition and I didn't want it to end. If you really like it go for it. And it has meaning to you so it' not a frivolous decision.

Personally, I think if you think outside the box and use some creativity you would be able to come up with something that ties them together but isnt exactly the same. Each child is unique, why not give them unique names?

I love the idea of linking children: I've done it myself. My daughters mn is Rose to honour my great aunt, and my second daughters mn is Iris to tie them together because they are both my beautiful flowers, and I love that Iris also means rainbow this is special to me as well. If we have a third daughter her mn will be Aurora and it ties in bbecause it is also colors in the sky, there is a goddess both named Iris and Aurora, and Rose is also a colour! If we have a son, the middle name Lawrence is of a river I grew up beside, so it is still a nature name.

Also if you're open to new experiences and memories.. you may find something else you wish to immortalize as your life is lived! Best of luck.

Why not? I'd like to add that I think Valentine is a perfectly lovely middle name!
I know of a couple whose three daughters are all named Mary(for religious and family reasons) with different middle names-they went by their middle names. I guess I wouldn't do this, but only because I think Mary is a beautiful name that I want my child to actually use.
